If you haven't been paying attention, you will have missed the fact that Verizon Wireless is investing like mad around the US to improve their mobile network. The quality of the wireless network was amazing to begin with and now this. VZW puts out a release every few days about a new region they are enhancing.

Perhaps all wireless companies are spending the same amount but if so they are not taking advantage of the free publicity that comes with putting our frequent press releases on their progress.

In my experience, companies who put out frequent releases do better than those who do not.

The more the editors in the world see your name surrounded by positive news the more likely they are to write nice things about you.

If you have any doubts, read to the end.

Today's release is about improving the network in Kansas, Missouri and Southern Illinois.

Covad reported a fourth quarter net loss of $11.9 million or $0.04 per share, compared to a net loss of $8.4 million or $0.03 per share in the previous year quarter.

Net revenues for the quarter increased to $121.6 million from $119.4 million in the last year quarter.

On average, five analysts polled by First Call/Thomson Financial expected loss of $0.01 per share, while analysts estimated revenues of $125.03 million for the fourth quarter.

For fiscal 2007, net loss was $43.0 million or $0.14 per share, compared to a net loss of $13.9 million or $0.05 per share in the last year.

Net revenues for the year were $484.2 million, up from $474.3 million in the prior year.

It seems the company's fortunes turned for the worse a few years back around the time the company stopped advertising and changed its focus from being an IP communications company to a broadband company. This move was accompanied by a management change as well.

I am not sure what the company's future holds but I keep hearing the question "Is Covad still around" from readers and attendees at shows. This is usually not a good sign.

Tom Keating has an excellent review of the Garmin nuvifone and after reading it I remain very impressed with what the company will be releasing soon. Let's look at the facts. Garmin's nuvi line is fantastic. I like the easy to use interface and most importantly I like the haptic feedback the device allows which basically means that vibrating feeling you get when you hit an on screen button.

I have an e-mail into the company which should clear this question up but for now, let's consider that this device has an amazing array of features.

If you were hoping for the day that you could fit a video projector in your pocket, perhaps that day is finally here. Of course this depends a bit on how big your pockets are. From this picture it seems that the new Samsung MBP-100 is about the size of the cell phone it can connect to.

I suppose the market for this device is people who occasionally need a projector but don't want to lug a full-sized one with them.

On the business communications side, the company has been having a good deal of trouble lately keeping its dealers happy. Numerous changes have cut into dealer margins and put some out of business according to my sources.

Quite often people are in places like a bar room brawl, a rain storm or even a war zone and they wish they could take crucial phone calls. After all, it could be an important caller letting you know for example that your Blackberry service is down.

Until now, when you were in such situations, you were out of luck... You had to let the call go into voicemail and catch it a bit later.

Thankfully, Plantronics has helped us solve this problem with the introduction of the Explorer 370, a headset that is designed to meet US military standards.

The Explorer 370 is certified to MIL-STD 810 standards issued by the United States Army's Developmental Test Command to prove that equipment qualified to the standard will survive in the field.

As you may know, Mobile World Congress kicks off this week and to get the ball rolling the event has put out some of the key terms you will be hearing more about this week. I have posted them here with their definitions in case you need to brush up on your acronyms.
